Carrie Underwood goes vegan

Country music star Carrie Underwood has revamped her diet plan and become a vegan.

The singer adopted a vegetarian lifestyle several years ago after discovering the long-term health benefits of cutting out meat, and the former “American Idol” star reveals she’s now avoiding animal products all together in a bid to boost her overall well-being.

She tells Self magazine, “I’ve been a vegetarian for seven years, but after seeing a friend who looked amazing and had recently gone vegan, I thought, ‘What’s holding me back?’ Now I’m 95-percent vegan.”

However, Underwood insists she’d consider adding dairy back into her eating regime if she could run her own farm.

She adds, “My veganism is based on a concern about where my food is coming from. In my perfect world, I’d have webcams wherever food is processed so I’d know how clean it is.

“I’ll never eat meat again, because I look and feel better without it, but if I could raise my own cows and chickens and produce my own eggs and cheese, it would be awesome! The food would taste better, because the animals would be happy!”
